Biological samples from the bodies of Abu Musab al-Zarqawi and his associates have been delivered to the FBI crime laboratory in Quantico, Virginia. "Biological materials listed as being from three different individuals, including al-Zarqawi, were received at the FBI laboratory," said special agent Ann Todd, the lab's spokeswoman. "FBI laboratory scientists will be working around the clock to conduct genetic testing." The biological samples, which the FBI would not describe, were flown to the United States by the military after al-Zarqawi and the others were killed in a US airstrike on a safe house north of Baghdad. The samples arrived Thursday night. DNA tests will compare the sample from al-Zarqawi with evidence taken from other terrorist safe houses, said John Miller, the FBI's assistant director in charge of public affairs. "It will give us a window to establish where he's been and may help us learn who's been with him," Miller said. The results are expected in three days. US authorities have already fingerprinted the body to confirm it is that of the terrorist leader.
